"No surgery for me," she said. "I did try Botox, unfortunately, but I got out of it and now I can finally move my face again."

Kidman said that getting the cosmetic treatments was an "unfortunate move" but is back to being "completely natural".

She added: "I wear sunscreen, I don't smoke and I take care of myself, and I am proud to say that. Anybody can do anything to themselves - I don't judge - but personally, I believe in being physically fit. That's how I was raised."

The Australian actress can be seen next in Park Chan-Wook's Stoker with Mia Wasikowska and Michael Goode, out on March 1.
